I live in a rental property in Australia, and every year some contactor guy comes and replaces my smoke alarm battery. When he gave it to me the voltage read 10.11v (I think).
After shorting it for a few seconds the voltage dropped to 9.6v, and is now hanging around at that voltage after messing with it a bit more. (plugging it into one of those clip on 9v battery LED torch things) - although now it's slowly climbing as I type.
As far as I can tell, that's pretty much a brand new 9v battery.
So if you want all you can eat, slightly used 9v batteries for masses of school projects or whatever, hit up your local rental management company for the name of the contractor they use. Do a search for "smoke detector battery replacement waste of the planet contractor law" (no offence to the contractors, just the law). My guy said they are all dumped, and not used in any way (I presume recycled or at least disposed of in some kind of decent way).
Waste not want not etc...
